Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740488, here are decompositions:

41 + 8740447 = 8740488
59 + 8740429 = 8740488
61 + 8740427 = 8740488
101 + 8740387 = 8740488
151 + 8740337 = 8740488
157 + 8740331 = 8740488
167 + 8740321 = 8740488
199 + 8740289 = 8740488

Showing the first eight; more decompositions exist.
